摘要： Compact x-ray devices, systems, and methods for capturing in tomosynthesis, two-dimensional radiography, fluoroscopy, and stereotactic imaging modes. In some embodiments, the compact x-ray imaging system includes an x-ray source array including spatially distributed x-ray focal spots and a digital area x-ray detector. In some embodiments, the imaging system includes an electronic switching device configured to alternate the imaging mode of the system. In some embodiments, the imaging system includes a mechanical support configured to enable a position and orientation of the x-ray source array and the digital area x-ray detector to be adjusted such that both upper and lower extremities of a patient can be imaged using various imaging modes while a position of the plurality of spatially distributed x-ray focal spots with respect to the digital area x-ray detector remains unchanged.
